Calendars are great to have in your house, but the problem with most of them is that despite cute pictures of kittens or baby turtles, the calendars you can buy at those pop-up kiosks in the mall don't actually get updated with the events in your life. Instructables user Piney wanted a smarter wall calendar, so they built one with a Raspberry Pi and a LCD screen.

To actually build the thing, you'll just need a Raspberry Pi, a cheap LCD screen, and some mounting tools. From there, the process is actually really simple and pretty much just uses some software hacks to get rid of the mouse cursor and make sure your Google Calendar is always open and full screen. That said, the end result, an always up-to-date calendar on your wall is a pretty awesome little trick. Plus, you won't have to worry about the calendar store selling out of your favorite Tolkien calendar every year. Head over to Instructables for the full guide.
